Veeruitstoot bij Rode Wouw Milvus milvus in Nederland

On 13 July 2020, near Ommen in the eastern Netherlands, a juvenile Red Kite of about 48 days old (based on maximum wing chord) was found beneath the nest (with two still on the nest), apparently unable to fly. The bird was taken to a rehabilitation centre, where it lost all flight feathers in the next week. The lost feathers had a constricted calamus, typical of the ‘pinching-off syndrome’. The feathers started the regrow in August and by 17 September the feathers were such that release was possible near its nest (but several secondaries were askew, possibly indicating a deformed calamus). Some 50 m away from the nest, some more pinched-off primaries had been found on 5 August, suggesting that one or both remaining chicks also had been afflicted with the pinching-off syndrome.
